The value placed in my table ends up being either "True" or "False".
So when I try to query the table based on that value with a stored procedure it doesn't work since its looking for a 1 or a 0.
I think the .ToString() is part of the problem but i don't know the syntax to have the value from the CheckBox.Checked to be written as 1s or 0s instead of true or false.
I am having two aspx pages(Page1.aspx,Page2.aspx).I am stioring values in Session in Page1.aspx and retriving the same values from Page2.aspx.But if the session value is null I am getting an error as 'Object reference not set to an instance of an object.'Here is my code..
I am designing an prototyping an app the needs to store images, similar to facebook. This will be a public facing site and I am not sure how many users I will end up with but what I am looking for is a way to efficiently retrieve them.
So far I am thinking of storing them in SQL Server varbinary columns. I have the upload code and the storage code for that. My concern is retrieving them. I can retireve and build the image tag on the fly but I am worried about having to hit the database for each one.
I have been thinking about getting all images for a user and caching them in the asp.net cache for 10 to 30 seconds. I have never had to do something like this so I would be interested in hearing a few different approaches. Obviously the images can vary in size and I was thinking about defining a size limit, but I haven't gotten that far yet.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
I am trying to retrieve a value from the row based on the user checking the checkbox but the only way it works is opposite of what I think it should be. The problem is I can only get the values if I set "If RowCheckBox.Checked = False" So I have rows returned in the gridview:
row1, record1 row2, record2 row3, record3
I want to check row1 and row3 and grab the values record1 and record3 I use:
Dim str As String Dim row As GridViewRow Dim index As Integer = dgrdSearchResults.SelectedIndex lblStatus.Text = index For Each row In dgrdSearchResults.Rows If index = -1 Then index = 0 End If Dim RowCheckBox As CheckBox = CType(dgrdSearchResults.Rows(index).FindControl("chkResults"), CheckBox) If RowCheckBox.Checked Then str = dgrdSearchResults.Rows(index).Cells(2).Text lblStatus.text = str End If index += 1 Next
With this code I basically step out even when I have rows checked. zaybe I am looking to much but I cannot get it to return the values I need unless I change "If RowCheckBox.Checked " to If RowCheckBox.Checked = "False"
I want to updated records according to all the checkbox which is checked on page1 page 2 and so on

I am storing image (jpeg) files into SQL server 2005 using MS Access Forms. When I try to read and render it on a webpage using ASP.net and C# code behind, it could not read it.
But if I write the image to SQL server using ASP.NET C# and then read it back using ASP.NET C#, it render the image just fine in the browser.
Does anyone know if Access write the blob is difference than ASP.NET write the blob into SQL server? I am using the same varbinary as my column in the database.
I need to display the checkbox selected values in a textbox... I have kept 18 separate checkboxes if user selects five checkboxes the values must be displayed in a single textbox followed by comma after each value..
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
I got a list of customers That I'm gone show in the gridview. I have added a checkbox infront of every customer so i can select what customers gone be used and passed to the next method. With a little bit of strugle I almost got everything working now except for this thing with keeping the values of checked customers when I page to the next page (2,3,4,5 ect).

I want to get Row Fields in Gridview on Checkbox Change inside gridview.I have checkbox column in grid, i want to get row details in msgbox as i select checkbox. On selected index change of checkbox inside ridview.Everytime i select checkbox, it gives msgbox for row details.
I am having gridview and i have check box for each row. There are 2 buttons ,accept and reject outside the gridview. If I click accept button, all the checked rows fields value should change to accept and if i click reject button all the checked rows column value should change to reject. There are 3 columns only one column will change.
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I have an html checkbox that controls a list of checkboxes. I want this checkbox to display in a sorta "null" state where it is neither true nor false. <HeaderTemplate> <div style="width:90px"> Toggle: <input id="chkAll" onclick="javascript:SelectAllCheckboxes(this);" runat="server" type="checkbox" /> </div> </HeaderTemplate>
- How can I uncheck a checkbox using client side code when the other checkbox is checked? - Is there a way to check server side on form submission that at least one check box is checked?

i am a beginer and i want to know how to store images in the database tables like pictures of the pizzas and when the user selects one of the pizza from the dropdownlist he sees the image of the selected pizza.
I'm building a web system and various clients will have alternate text for default instances throughout the site. One place is the main nav but there are others. The default may be "project" but they may want to call it "event".I'm heading down the road of calling all the terminology settings (there's a list of about 15) and creating an ArrayList that has the id and either the default or their replacement as the items in the ArrayList.I've also got a enum key list called TermKey that has the defaults and the corresponding ID number.
Throughout the code I'll reference TermKey.Project and then do one of these things that I see as options. 1-pull the text from the session (if the client has set it to "event" then the text "event" will be waiting for the call there)2-pull the text from the database every time I need it.3-pull the client's list each time a page loads.Some thoughts on the impact each way or if there is a best practice for
